An object of the present invention is to provide an induction heating cooker with improved assemblability, and with which a reduction in the temperature sensing precision of an infrared sensor can be suppressed and a reduction in the thickness of the induction heating cooker can be achieved. To this end, the induction heating cooker of the present invention includes a ductthat forms a cooling air path for guiding the cooling air produced by the air blowerto a control circuitand to an infrared sensor. The infrared sensorand the control circuitare disposed at positions lower than the top wall of the duct

Induction heating cooker

To reduce the air exhausted to outside a main body after cooling a heat generating component from being taken in again from an intake port. The flow of cooling wind cooled the heat generating component is discharged from an exhaust port at other than a first peripheral wall with the flow bent inside the main body. When rectified inside the main body and discharged from the exhaust port, the cooling wind grows to a flow speed of a certain extent to become an exhaust air that a flowing direction is clearly defined, so that it is less likely to be taken in again from the intake port, it is less likely to be subjected to the influence of obstacles of the exhaust port, use can be made in a kitchen cabinet of the intake and exhaust air at the back side, and it is satisfactory and is less likely to be damaged without involving sense of unpleasantness by the exhaust air to the user.

Induction cooking appliance

An induction cooking device includes a control unit and a plurality of light-emitting parts. The control unit includes a heating control unit that controls the output of an inverter circuit and a light-emission control unit that controls the light emission. When receiving a command for starting with one heating coil, the control unit turns on only the light-emitting parts provided near the outer circumference of the heating coil for starting heating, and when receiving a command for starting heating with two or more adjacent heating coils, the control unit turns off the light-emitting parts disposed between the heating coils for starting heating among the light-emitting parts provided near the outer circumference of each one of the heating coils for starting heating, and turns on the remaining light-emitting parts.

Induction cooking device

An induction heating device includes a top plate arranged to have an object placed thereon, a heating coil provided under below the top plate for heating the object, a sensor provided under the top plate for detecting a temperature of the object, a judging unit for judging whether or not the object is positioned directly above the sensor, a controller operable to allow the heating coil to heat the object in response to the temperature detected by the sensor detecting, and a position indicator provided at the top plate for indicating a position of the sensor. The position indicator includes a detectable area of the sensor, and is larger than the detectable area. This induction heating device securely positions the object directly above the sensor and detects a temperature of the object accurately, hence heating the object accurately at a predetermined temperature.

Induction heating device

Plural induction heating coils for inductively heating to-be-heated object are provided under a top plate on which to-be-heated object is placed, and plural inverter circuits for supplying high-frequency currents to the plural induction heating coils, respectively, are adapted to be cooled by cooling air flows from cooling portions, and placed in a longitudinal row along the cooling air flows, in air-flow blowing path spaces through which cooling air flows from the cooling portions are blown, so as to facilitate cooling designing for an induction heating device and to improve the cooling performance of the induction heating device.

An induction heating cooking apparatus includes a magnetic flux-shielding plateto restrain magnetic flux leakage from a heating coiland define a cooling air trunk, through which cooling air from a fanpasses. An infrared sensorfor detecting infrared rays emitted from a cooking containerand a control circuitfor controlling an output of a heating coildepending on an output from the infrared sensorare accommodated within the same space with respect to the magnetic flux-shielding plateto thereby enhance assemblage. Also, the infrared sensoris mainly cooled by cooling air passing through a cooling air trunkto thereby enhance the cooling efficiency of the infrared sensorand conduct correct temperature detection.

Induction heating cooking apparatus

The present invention provides an operation device which has a stable operation feeling with a simple configuration and has a high reliability and an excellent operability. An electrode terminal portion which is arranged just below an operation region on a top plate made of a material having an electric insulating property, and serves as an electrostatic capacity type touch switch has a detection portion which comes into close contact with a back surface of the operation region, a spring portion which has an elastic force pressing the detection portion to the back surface of the top plate, and a slide portion which is movably retained in the guide holder.

Operation device and heating cooker using operation device

A portable heat transfer apparatus including a combustion device, a thermoelectric convertor for receiving the heat of the combustion device at its high temperature side, transferring the heat from its low temperature side to a heat exchanger, and generating electric power depending on the temperature difference between the high temperature side and low temperature side. A heat medium forced circulating device is driven by the power generated from the thermoelectric converter for transferring heat medium to the heat exchanger. Also provided is a heat releasing device for circulating and releasing the heat medium exchanged of heat in the heat exchanger. Therefore, the heat exchanger can be heated through the thermoelectric converter while heating the thermoelectric converter with the combustion device, and by heating with the heat exchanger. The temperature difference between the high temperature side and low temperature side of the thermoelectric converter can be obtained rationally and sufficiently. Therefore, the apparatus is reduced in size and weight, and it is convenient for portable use.

Heat transfer apparatus

A fuel tank stores fuel gas. A catalytic burning section is connected to the fuel tank for generating heat based on an oxidative reaction between the fuel supplied from the fuel tank and air. The fuel tank and the catalytic burning section are assembled as a catalytic heat generating apparatus. The catalytic heat generating apparatus is detachably installed in a housing of a heater section. The heater section has both ends provided with a pair of belt portions wound around a user's body.

Portable warmer suitable for a body

A catalytic combustion heating device 3 for generating heat by oxidation reaction of fuel gas stored in a fuel tank 24 and air in a combustion unit 29 is installed in a mount 4 provided in a jacket 1. The mount 4 is fastened to the waist of the body wearing the jacket 1 by a holding band 9, and the load applied on the shoulders through the jacket is lessened and comfort is improved. Thus, a warming jacket capable of warming the body comfortably is obtained.
